Description

Technical Field

[0001] The invention belongs to the technical field of gasification ash separation, and in particular relates to a flotation device and a flotation method of gasification ash. Background Art

[0002] Ash flotation equipment is a special mechanical equipment used to effectively separate carbon and ash in ash. Through specific process flow and reagents, the residual carbon in the ash can be effectively recovered.

[0003] The existing flotation equipment is used as follows: the pre-treated gasified ash is mixed with water to form a slurry, and then a specific flotation agent (such as a collector, a frother, etc.) is added, and the slurry is transported to a flotation machine or a spiral chute for sorting through a slurry pump. Since there are fine slag and coarse slag in the ash, for certain coarse slags of a specific particle size, such as +0.125mm particles, it is easy to sink in the slurry mixing barrel, and it is difficult to effectively separate the carbon and ash in the ash, resulting in a low resource recovery rate. A common improvement method is to grind the ash with a grinder. For example, the invention patent with publication number CN117427784A pours the ash into a grinder, which causes the fine slag and coarse slag in the ash to be ground together. In this process, the fine slag is ground into finer particles. Since the quality of the fine slag after grinding is reduced, the fine slag is easy to adhere to the inner wall of the slurry mixing barrel during the flotation process, and it needs to be manually cleaned later. Summary of the invention

[0004] The purpose of the present invention is to provide a flotation device and a flotation method for gasified ash to solve the technical problems in the prior art in view of the deficiencies in the prior art.

[0005] The object of the present invention can be achieved by the following technical scheme: a flotation device for gasified ash, comprising a box body, a slurry mixing component and a flotation machine, a liquid medicine box and a quantitative feeding component are installed on the top of the box body, the quantitative feeding component is connected to the screening component, the screening component comprises a material distribution bag, a screening net and a rubber discharge pipe, the material distribution bag is installed with a screening net, both sides of the bottom of the material distribution bag are installed with rubber discharge pipes, a lifting mixing box is installed in the box body, the rubber discharge pipe faces the mixing box, two rotating plates are installed at the bottom of the material distribution bag, the two rotating plates rotate through a rotating shaft, the screening component and the mixing box are connected through a transmission component, the mixing box is connected with the slurry mixing component through a connecting pipe, and the slurry mixing component is connected with the flotation machine;

[0006] The transmission assembly comprises a press table, a second rack and a first rack. The second rack is installed on the rotating shaft, a gear is installed on the inner wall of the box body, and the first rack is installed on the mixing box. The second rack is meshed with the first rack through the gear.

[0007] As a further optimization or improvement of the present solution, the screening material assembly further includes a flexible mesh plate and an air cavity. An air cavity is provided at the bottom of the material distribution bag, and the air cavity is separated by a flexible mesh plate. The aperture of the flexible mesh plate is smaller than that of the screening material net.

[0008] As a further optimization or improvement of the present solution, the transmission assembly further includes a pressing roller, the pressing roller is mounted on the pressing platform, and a rounded transition area is provided on the top of the pressing platform.

[0009] As a further optimization or improvement of the present scheme, the quantitative feeding assembly includes a material storage box and a quantitative block. The bottom of the material storage box is configured with a closed opening. The quantitative block is installed on the discharge port of the material storage box. The quantitative block is driven by a pushing cylinder. A connecting plate for fixing the pushing cylinder is installed in the material storage box. The quantitative block is connected to the material distribution bag through a connecting block.

[0010] As a further optimization or improvement of the present solution, the slurry mixing assembly includes a slurry mixing barrel and a stirring blade, the stirring blade is installed inside the slurry mixing barrel, a storage table is installed inside the slurry mixing barrel, and a lifting and weighing assembly is installed inside the storage table.

[0011] As a further optimization or improvement of this solution, the lifting and weighing assembly includes a lifting cylinder and a compression spring. The lifting cylinder is installed in the storage table, and the output end of the lifting cylinder is connected to the weighing plate, and the weighing plate is connected to the mixing box through the compression spring.

[0012] As a further optimization or improvement of the present solution, a pressing plate is installed on the mixing box, and one end of the pressing plate is located above the rubber discharge pipe.

[0013] As a further optimization or improvement of the present solution, the screening material assembly further includes a return spring, and the return spring connects the two rotating plates.

[0014] A flotation method for gasified ash, the method is applied to the flotation equipment for gasified ash as described above, the method comprising the following steps:

[0015] Step S1: Pour the ash into the storage box, and drive the quantitative block to rise by the push cylinder. When one end of the quantitative block enters the storage box from the discharge port of the storage box, the ash inside the storage box will automatically enter the two sides of the quantitative block, and then the push cylinder drives the quantitative block to descend; when the other end of the quantitative block is away from the discharge port of the storage box, the ash stored in the quantitative block falls into the material distribution bag and is screened by the screening net;

[0016] Step S2: As the fine slag particles in the ash enter the mixing box, the fine slag inside the mixing box gradually increases. As the weight of the mixing box increases, the mixing box begins to press the compression spring and move downward. When the amount of fine slag in the mixing box is about to reach a specified amount, the pressure plate on the mixing box begins to press the rubber discharge pipe to control the amount of fine slag entering the mixing box through the rubber discharge pipe to prevent the amount of fine slag in the mixing box from exceeding the specified amount.

[0017] Step S3: When the amount of fine slag inside the mixing box reaches a specified amount, the mixing box moves upward. During this process, the mixing box pulls the rotating shaft and the material distribution bag thereon downward through the transmission assembly. When the rotating shaft is pulled, the two rotating plates rotate along the rotating shaft and clamp the rubber discharge pipe;

[0018] Step S4: When the mixing box pulls the material distribution bag through the transmission assembly, the material distribution bag is stretched, and as the mixing box moves upward, when the stretched material distribution bag passes through the rounded transition area on the press table, the coarse residue inside the material distribution bag is flattened inside, making it convenient for the press table and the press roller to crush the coarse residue. As the mixing box moves upward, the press table and the press roller crush the coarse residue inside the material distribution bag;

[0019] Step S5: As the mixing box moves upward, the output port of the medicine box is inserted into the mixing box and a certain amount of water and medicine are injected into the mixing box. During this process, the gate valve on the connecting pipe is opened to allow the slurry mixed with fine slag and water in the mixing box to rush into the slurry mixing component for stirring, and then the stirred slurry is pumped into the flotation machine, so that the flotation machine floats the slurry.

[0020] As a further optimization or improvement of this solution, step S1 specifically includes the following steps:

[0021] Step S11: During the lifting and lowering process of the quantitative block, the quantitative block pulls the material distribution bag through the connecting block, causing the ash inside the material distribution bag to bump, thereby accelerating the fine slag in the ash to pass through the screening net and enter the mixing box;

[0022] Step S12: The amount of fine slag inside the mixing box can be measured by a weighing plate;

[0023] Step S13: The amount of ash entering the material distribution bag is calculated by the lifting times of the quantitative block, and then the amount of fine slag in the ash is measured by the weighing plate to calculate the amount of fine slag in the ash.

[0024] Beneficial effects of the present invention:

[0025] (1) When the present invention is in use, ash is poured into the storage box, and the quantitative block is driven to rise by the push cylinder. When one end of the quantitative block enters the storage box from the discharge port of the storage box, the ash inside the storage box automatically enters the two sides of the quantitative block, and then the push cylinder drives the quantitative block to descend; when the other end of the quantitative block is away from the discharge port of the storage box, the ash stored in the quantitative block falls into the distribution bag and is screened by the screening net; in the process of the quantitative block being raised and lowered, the quantitative block pulls the distribution bag through the connecting block, so that the ash inside the distribution bag is bumpy, thereby improving the screening efficiency of the screening net. The screening net can pass the particles smaller than 0.125 mm in the ash into the mixing box through the rubber discharge pipe, thereby realizing a single quantitative discharge of the quantitative block. The present invention screens the fine slag and the coarse slag in the ash, grinds the coarse slag separately, and avoids the phenomenon that the fine slag after grinding is easily adhered to the inner wall of the slurry mixing barrel.

[0026] (2) In the present invention, when the amount of fine slag inside the mixing box reaches a specified amount, the lifting cylinder controls the mixing box to rise. During this process, the mixing box pulls the rotating shaft and the material distribution bag thereon downward through the transmission assembly. When the rotating shaft is pulled, the two rotating plates rotate along the rotating shaft and clamp the rubber discharge pipe, thereby protecting the rubber discharge pipe;

[0027] When the mixing box pulls the distribution bag through the transmission assembly, the distribution bag is stretched. At the same time, as the mixing box moves upward, when the stretched distribution bag passes through the rounded transition area on the press table, the coarse slag inside the distribution bag is flattened inside, making it convenient for the press table and the press roller to crush the coarse slag. As the mixing box moves upward, the press table and the press roller crush the coarse slag inside the distribution bag and grind the coarse slag into a flotation requirement of less than 0.125 mm.

[0028] (3) As the ash fine slag particles smaller than 0.125 mm in the present invention enter the mixing box, the fine slag inside the mixing box gradually increases, and the overall weight of the mixing box increases accordingly. As the weight of the mixing box increases, the mixing box begins to press the compression spring and move downward. When the amount of fine slag in the mixing box is about to reach a specified amount, the pressure plate on the mixing box begins to press the rubber discharge pipe to control the amount of fine slag entering the mixing box through the rubber discharge pipe, thereby preventing the amount of fine slag in the mixing box from exceeding the specified amount.

[0029] Specifically, when the amounts of fine residues inside the two mixing boxes are not equal, the mixing box with more fine residues moves downward more, and the pressure plate on this mixing box presses the rubber discharge pipe to a greater extent, and the amount of fine residues entering this mixing box through the rubber discharge pipe is reduced. As a result, the amount of fine residues passing through the other mixing box with less fine residues increases relatively, until the amounts of fine residues inside the two mixing boxes are balanced.

[0030] (4) The present invention can measure the amount of fine slag inside the mixing box by means of the weighing plate at the bottom of the compression spring. At the same time, since the amount of ash slag that can be collected each time the quantitative block is lifted or lowered is fixed, the amount of ash slag entering the distribution bag is calculated by the number of times the quantitative block is lifted or lowered. Then, the amount of fine slag in the ash slag is measured by the weighing plate, and then the amount of fine slag in the ash slag is calculated, which is convenient for recording the ash slag status.

[0031] (5) During the lifting process of the quantitative block in the present invention, the quantitative block pulls the material distribution bag through the connecting block, so that the material distribution bag and the screen mesh inside it are shaken. The shaking of the screen mesh drives the ash stuck inside the screen mesh to fall off, thereby reducing the situation where the ash blocks the screen mesh;

[0032] Secondly, the present invention can also drive the two rotating plates to rotate along the rotating shaft and clamp the rubber discharge pipe by pulling the rotating shaft. At the same time, the rotation of the rotating plates will squeeze the air cavity, and the air pressure inside the air cavity will impact upward through the flexible mesh plate, flushing the particles blocked inside the screen mesh out of the screen mesh.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 7 The object of the present invention can be achieved by the following technical scheme: a flotation device for gasified ash, which includes a box body 1, a slurry mixing component 2 and a flotation machine 3, a liquid medicine box 4 and a quantitative feeding component 5 are installed on the top of the box body 1, and the quantitative feeding component 5 is connected to the screening component 6, the screening component 6 includes a material distribution bag 601, a screening net 602 and a rubber discharge pipe 603, the screening net 602 is installed in the material distribution bag 601, and rubber discharge pipes 603 are installed on both sides of the bottom of the material distribution bag 601, a lifting mixing box 7 is installed in the box body 1, and the rubber discharge pipe 603 faces the mixing box 7, two rotating plates 605 are installed at the bottom of the material distribution bag 601, and the two rotating plates 605 are rotated by a rotating shaft 607, the screening component 6 and the mixing box 7 are connected by a transmission component 9, the mixing box 7 is connected to the slurry mixing component 2 by a connecting pipe 8, and the slurry mixing component 2 is connected to the flotation machine 3;

[0044] The transmission assembly 9 includes a press table 901, a second rack 905 and a first rack 903. The second rack 905 is installed on the rotating shaft 607, a gear 904 is installed on the inner wall of the box body 1, and the first rack 903 is installed on the mixing box 7. The second rack 905 is meshed with the first rack 903 through the gear 904.

[0045] Specifically, the transmission assembly 9 further includes a pressure roller 902 . The pressure roller 902 is installed on the pressure platform 901 , and a rounded transition area is provided on the top of the pressure platform 901 .

[0046] It should be noted that the outer layer of the material distribution bag 601 is made of synthetic leather and rubber. The synthetic leather can ensure the shape of the material distribution bag 601, and the rubber improves the elasticity of the material distribution bag 601; the inner layer is made of metal material to ensure that the material distribution bag 601 has the characteristics of being soft on the outside and hard on the inside, so that the coarse residue inside the material distribution bag 601 can be crushed by the pressure roller 902 while the material distribution bag 601 is pulled.

[0047] It should be noted that when the present invention is in use, ash is poured into the storage box 501, and the push cylinder 503 is started. The push cylinder 503 drives the quantitative block 504 to rise. When one end of the quantitative block 504 enters the storage box 501 from the discharge port of the storage box 501, the ash inside the storage box 501 automatically enters the two sides of the quantitative block 504. Then the push cylinder 503 drives the quantitative block 504 to descend. In this process, the troughs on both sides of the quantitative block 504 are filled with ash. When the quantitative block 504 When the other end is away from the discharge port of the storage box 501, the ash stored in the quantitative block 504 falls into the material distribution bag 601 and is screened by the screening net 602; during the lifting and lowering process of the quantitative block 504, the quantitative block 504 pulls the material distribution bag 601 through the connecting block 505, so that the ash inside the material distribution bag 601 is bumpy, thereby improving the screening efficiency of the screening net 602, and the screening net 602 can pass the particles smaller than 0.125 mm in the ash into the mixing box 7 through the rubber discharge pipe 603;

[0048] When the amount of fine slag inside the mixing box 7 reaches a specified amount, the lifting cylinder 1101 controls the mixing box 7 to rise. During this process, the mixing box 7 pulls the rotating shaft 607 and the material distribution bag 601 thereon downward through the transmission assembly 9. When the rotating shaft 607 is pulled, the two rotating plates 605 rotate along the rotating shaft 607 and clamp the rubber discharge pipe 603 to protect the rubber discharge pipe 603.

[0049] When the mixing box 7 pulls the distribution bag 601 through the transmission assembly 9, the distribution bag 601 is stretched, and as the mixing box 7 moves upward, when the stretched distribution bag 601 passes through the rounded transition area on the press table 901, the coarse slag inside the distribution bag 601 is flattened inside it, making it convenient for the press table 901 and the press roller 902 to crush the coarse slag. As the mixing box 7 moves upward, the press table 901 and the press roller 902 crush the coarse slag inside the distribution bag 601 and grind the coarse slag into a flotation requirement of less than 0.125 mm.

[0050] See also Figure 3-Figure 4 The screening component 6 also includes a flexible mesh plate 608 and an air cavity 604 . The air cavity 604 is opened at the bottom of the material distribution bag 601 . The air cavity 604 is separated by the flexible mesh plate 608 . The aperture of the flexible mesh plate 608 is smaller than that of the screening net 602 .

[0051] It should be noted that dust-proof cloth is installed on the holes of the flexible mesh plate 608 to effectively prevent finer slag particles from entering the air cavity 604 when the screening net 602 screens the ash. The flexible mesh plate 608 is made of a plastic plate with a certain degree of flexibility.

[0052] During the process of screening ash by the screening net 602, there is a possibility that particles in the ash may block the screening net 602. During the lifting and lowering of the quantitative block 504 in the present invention, the quantitative block 504 pulls the distribution bag 601 through the connecting block 505, so that the distribution bag 601 and the screening net 602 inside it are shaken. The shaking of the screening net 602 drives the ash stuck inside the screening net 602 to fall off, thereby reducing the possibility of ash blocking the screening net 602.

[0053] The present invention drives the two rotating plates 605 to rotate along the rotating shaft 607 and clamp the rubber discharge tube 603 by pulling the rotating shaft 607. At the same time, the rotation of the rotating plates 605 will squeeze the air cavity 604. The air pressure inside the air cavity 604 will impact upward through the flexible mesh plate 608, and the particles blocked inside the screen mesh 602 will be flushed out of the screen mesh 602.

[0054] See also Figure 2-Figure 7 The quantitative feeding component 5 includes a storage box 501 and a quantitative block 504. The bottom of the storage box 501 is closed. The quantitative block 504 is installed on the discharge port of the storage box 501. The quantitative block 504 is driven by a pushing cylinder 503. A connecting plate 502 for fixing the pushing cylinder 503 is installed in the storage box 501. The quantitative block 504 is connected to the material distribution bag 601 through a connecting block 505.

[0055] It should be noted that a dustproof shell is installed outside the push cylinder 503 to prevent the ash inside the storage box 501 from affecting the operation of the push cylinder 503 and protect the push cylinder 503. The quantitative block 504 is set in an I-shape, and the ash can be stored on both sides of the quantitative block 504. The bottom plate of the quantitative block 504 is set tilted, and the tilted bottom plate can facilitate the discharge of the ash in the quantitative block 504.

[0056] It should be noted that the slurry required for flotation is obtained by mixing the fine slag in the ash with water and reagents. Since the fine slag in the slurry is in a fixed ratio with water and reagents, the amount of fine slag needs to be controlled to a specified amount to avoid the slurry exceeding or not being within the fixed limit each time due to the non-fixed amount of fine slag.

[0057] The present invention pours ash into the storage box 501, starts the push cylinder 503, and the push cylinder 503 drives the quantitative block 504 to rise. When one end of the quantitative block 504 enters the storage box 501 from the discharge port of the storage box 501, the ash inside the storage box 501 automatically enters the two sides of the quantitative block 504, and then the push cylinder 503 drives the quantitative block 504 to descend. In this process, the troughs on both sides of the quantitative block 504 are full of ash. When the other end of the quantitative block 504 is away from the discharge port of the storage box 501, the ash inside the storage box 501 automatically enters the two sides of the quantitative block 504. When the material storage box 501 is discharged, the ash stored in the quantitative block 504 falls into the material distribution bag 601 and is screened by the screening net 602; during the lifting and lowering process of the quantitative block 504, the quantitative block 504 pulls the material distribution bag 601 through the connecting block 505, so that the ash inside the material distribution bag 601 is bumpy, thereby improving the screening efficiency of the screening net 602, and the screening net 602 can pass the particles smaller than 0.125 mm in the ash into the mixing box 7 through the rubber discharge pipe 603;

[0058] As the fine slag particles smaller than 0.125 mm in the ash enter the mixing box 7, the fine slag inside the mixing box 7 gradually increases, and the overall weight of the mixing box 7 increases accordingly. As the weight of the mixing box 7 increases, the mixing box 7 begins to press the compression spring 1103 and move downward. When the amount of fine slag in the mixing box 7 is about to reach a specified amount, the pressing plate 10 on the mixing box 7 begins to press the rubber discharge pipe 603 to control the amount of fine slag entering the mixing box 7 through the rubber discharge pipe 603, so as to prevent the amount of fine slag in the mixing box 7 from exceeding the specified amount. Quantification; when the amounts of fine residues in the two mixing boxes 7 are not equal, the mixing box 7 with more fine residues moves downward more, and the pressing plate 10 on this mixing box 7 presses the rubber discharge pipe 603 to a greater extent, and the amount of fine residues entering this mixing box 7 through the rubber discharge pipe 603 is reduced. As a result, the amount of fine residues passing through the other mixing box 7 with less fine residues increases relatively, until the amounts of fine residues in the two mixing boxes 7 are balanced; then, water and chemicals in equal proportions are injected into the mixing box 7 through the medicine liquid tank 4 and mixed into a slurry.

[0059] The amount of fine slag inside the mixing box 7 can be measured by the weighing plate 1102 at the bottom of the compression spring 1103. At the same time, since the amount of ash that can be collected each time the quantitative block 504 is lifted or lowered is fixed, the amount of ash entering the distribution bag 601 is calculated by the number of times the quantitative block 504 is lifted or lowered, and then the amount of fine slag in the ash is measured by the weighing plate 1102, and then the amount of fine slag in the ash is calculated, which is convenient for recording the ash status.

[0060] See also Figure 2 The slurry mixing component 2 includes a slurry mixing barrel 201 and a stirring blade 203 . The stirring blade 203 is installed inside the slurry mixing barrel 201 . A storage table 202 is installed inside the slurry mixing barrel 201 . A lifting and weighing component 11 is installed inside the storage table 202 .

[0061] It should be noted that the fine slag in the mixing box 7 is mixed with water and reagents in a fixed ratio and then discharged into the slurry mixing barrel 201 , where it is stirred and mixed by the stirring blades 203 in the slurry mixing barrel 201 and floated by the flotation machine 3 .

[0062] See also Figure 3-Figure 4 The lifting and weighing assembly 11 includes a lifting cylinder 1101 and a compression spring 1103. The lifting cylinder 1101 is installed in the storage table 202. The output end of the lifting cylinder 1101 is connected to the weighing plate 1102, and the weighing plate 1102 is connected to the mixing box 7 through the compression spring 1103.

[0063] Specifically, a pressing plate 10 is installed on the mixing box 7 , and one end of the pressing plate 10 is located above the rubber discharge pipe 603 .

[0064] See also Figure 3 As shown, a feed port for feeding materials to the mixing box 7 is provided on the pressing plate 10. During use of the device, water and medicine can be injected into the mixing box 7 by inserting the output port of the medicine liquid box 4 into the feed port.

[0065] See also Figure 5 The screening material assembly 6 also includes a return spring 606 , and the return spring 606 connects the two rotating plates 605 .

[0066] It should be noted that the reset spring 606 is mainly used to reset the rotating plate 605. When the two rotating plates 605 rotate, the rotating plates 605 squeeze the reset spring 606. When the rotating plates 605 are reset, the reset spring 606 resets and drives the two rotating plates 605 to unfold.

[0067] See also Figure 1-Figure 7 As shown, the present invention is a flotation method for gasified ash, which is applied to the flotation equipment for gasified ash as described in the above embodiment, and comprises the following steps:

[0068] Step S1: Pour the ash into the storage box 501, and drive the quantitative block 504 to rise by the push cylinder 503. When one end of the quantitative block 504 enters the storage box 501 from the discharge port of the storage box 501, the ash inside the storage box 501 will automatically enter the two sides of the quantitative block 504, and then the push cylinder 503 drives the quantitative block 504 to descend; when the other end of the quantitative block 504 is away from the discharge port of the storage box 501, the ash stored in the quantitative block 504 falls into the material distribution bag 601 and is screened by the screening net 602;

[0069] Step S2: As the fine slag particles in the ash enter the mixing box 7, the fine slag inside the mixing box 7 gradually increases. As the weight of the mixing box 7 increases, the mixing box 7 starts to press the compression spring 1103 and move downward. When the amount of fine slag in the mixing box 7 is about to reach a specified amount, the pressing plate 10 on the mixing box 7 starts to press the rubber discharge pipe 603 to control the amount of fine slag entering the mixing box 7 through the rubber discharge pipe 603, so as to prevent the amount of fine slag in the mixing box 7 from exceeding the specified amount.

[0070] Step S3: When the amount of fine slag inside the mixing box 7 reaches a specified amount, the mixing box 7 moves upward. During this process, the mixing box 7 pulls the rotating shaft 607 and the material distributing bag 601 thereon downward through the transmission assembly 9. When the rotating shaft 607 is pulled, the two rotating plates 605 rotate along the rotating shaft 607 and clamp the rubber discharge pipe 603.

[0071] Step S4: When the mixing box 7 pulls the material distribution bag 601 through the transmission assembly 9, the material distribution bag 601 is stretched, and as the mixing box 7 moves upward, when the stretched material distribution bag 601 passes through the rounded transition area on the press table 901, the coarse residue inside the material distribution bag 601 is flattened inside, which is convenient for the press table 901 and the press roller 902 to crush the coarse residue. As the mixing box 7 moves upward, the press table 901 and the press roller 902 crush the coarse residue inside the material distribution bag 601;

[0072] Step S5: As the mixing box 7 moves upward, the output port of the medicine tank 4 is inserted into the mixing box 7 and a certain amount of water and medicine are injected into the mixing box 7. During this process, the gate valve on the connecting pipe 8 is opened to allow the slurry mixed with fine slag and water in the mixing box 7 to rush into the slurry mixing component 2 for stirring, and then the stirred slurry is pumped into the flotation machine 3, so that the flotation machine 3 floats the slurry.

[0073] like Figure 2-Figure 3 As shown, as a preferred embodiment of the present invention, the step S1 specifically includes the following steps:

[0074] Step S11: During the lifting and lowering process of the quantitative block 504, the quantitative block 504 pulls the material distribution bag 601 through the connecting block 505, so that the ash inside the material distribution bag 601 bumps, and accelerates the fine slag in the ash to pass through the screening net 602 and enter the mixing box 7;

[0075] Step S12: The amount of fine slag inside the mixing box 7 can be measured by the weighing plate 1102;

[0076] Step S13: The amount of ash entering the material distribution bag 601 is calculated by the lifting times of the quantitative block 504, and then the amount of fine slag in the ash is measured by the weighing plate 1102 to calculate the amount of fine slag in the ash.

[0077] The implementation principle of the present invention is as follows: when in use, ash is poured into the storage box 501, and the push cylinder 503 is started. The push cylinder 503 drives the quantitative block 504 to rise. When one end of the quantitative block 504 enters the storage box 501 from the discharge port of the storage box 501, the ash inside the storage box 501 automatically enters the two sides of the quantitative block 504. Then the push cylinder 503 drives the quantitative block 504 to descend. In this process, the grooves on both sides of the quantitative block 504 are filled with ash. When the quantitative block 504 When the other end is away from the discharge port of the storage box 501, the ash stored in the quantitative block 504 falls into the material distribution bag 601 and is screened by the screening net 602; during the lifting and lowering process of the quantitative block 504, the quantitative block 504 pulls the material distribution bag 601 through the connecting block 505, so that the ash inside the material distribution bag 601 is bumpy, thereby improving the screening efficiency of the screening net 602, and the screening net 602 can pass the particles smaller than 0.125 mm in the ash into the mixing box 7 through the rubber discharge pipe 603;

[0078] As the fine slag particles smaller than 0.125 mm in the ash enter the mixing box 7, the fine slag inside the mixing box 7 gradually increases, and the overall weight of the mixing box 7 increases accordingly. As the weight of the mixing box 7 increases, the mixing box 7 begins to press the compression spring 1103 and move downward. When the amount of fine slag in the mixing box 7 is about to reach the specified amount, the pressing plate 10 on the mixing box 7 begins to press the rubber discharge pipe 603 to control the amount of fine slag entering the mixing box 7 through the rubber discharge pipe 603, so as to prevent the amount of fine slag in the mixing box 7 from exceeding the specified amount. When the amounts of fine slag inside the two mixing boxes 7 are not equal, the mixing box 7 with a larger amount of fine slag moves downward more, the pressing plate 10 on this mixing box 7 presses the rubber discharge pipe 603 to a greater extent, and the amount of fine slag entering this mixing box 7 through the rubber discharge pipe 603 is reduced. As a result, the amount of fine slag passing through the other mixing box 7 with a smaller amount of fine slag increases relatively, until the amounts of fine slag inside the two mixing boxes 7 are balanced.

[0079] The amount of fine slag inside the mixing box 7 can be measured by the weighing plate 1102 at the bottom of the compression spring 1103. At the same time, since the amount of ash that can be collected each time the quantitative block 504 is lifted or lowered is fixed, the amount of ash entering the distribution bag 601 is calculated by the number of times the quantitative block 504 is lifted or lowered, and then the amount of fine slag in the ash is measured by the weighing plate 1102, and then the amount of fine slag in the ash is calculated, which is convenient for recording the ash status.

[0080] When the amount of fine slag inside the mixing box 7 reaches a specified amount, the pressing plate 10 blocks the rubber discharge pipe 603, and the lifting cylinder 1101 controls the mixing box 7 to rise. During this process, the mixing box 7 pulls the rotating shaft 607 and the material distribution bag 601 thereon downward through the transmission assembly 9. When the rotating shaft 607 is pulled, the two rotating plates 605 rotate along the rotating shaft 607 and clamp the rubber discharge pipe 603, thereby protecting the rubber discharge pipe 603.

[0081] When the mixing box 7 pulls the distribution bag 601 through the transmission assembly 9, the distribution bag 601 is stretched, and as the mixing box 7 moves upward, when the stretched distribution bag 601 passes through the rounded transition area on the press table 901, the coarse slag inside the distribution bag 601 is flattened inside it, making it convenient for the press table 901 and the pressure roller 902 to crush the coarse slag. As the mixing box 7 moves upward, the press table 901 and the pressure roller 902 crush the coarse slag inside the distribution bag 601, so that the coarse slag can meet the flotation requirements of less than 0.125 mm.

[0082] As the mixing box 7 moves upward, the output port of the medicine tank 4 is inserted into the mixing box 7 and a certain amount of water and medicine are injected into the mixing box 7. During this process, the gate valve on the connecting pipe 8 is opened to allow the slurry mixed with fine slag and water in the mixing box 7 to rush into the slurry mixing component 2 for stirring, and then the stirred slurry is pumped into the flotation machine 3, so that the flotation machine 3 floats the slurry.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
